Multimodality Imaging in the Evaluation of Cardiovascular Manifestations of Malignancy
Figure 6
Mitral annular calcification (MAC). A classic “pseudotumour” MAC is seen in older patients, often with a history of diabetes or hypertension. It presents as focal mass-like lesions most frequently adjacent to the lateral mitral annulus ((a) and (b), white arrow). In this example the signal characteristics on CMR are typically being low signal on T1-weighted images (a) and T2-weighted images (b). Its relation to the posterior mitral annulus is well appreciated on the short axis bright-blood cine view ((c), white arrow). Noncontrast MDCT excludes any residual diagnosis about the diagnosis—the mass is of very high attenuation consistent with calcium ((d), white arrow).
